XF 1.1How long before I delete the old 'vB' Folder? (Redirects in place)

Well-known member

We migrated from vB + vBSEO (located in /forum/ ) to XF located in ( /community ) . I see in Google ( through the site:www.crazyengineers.com/forum/ search that about 400 old URLs are still listed in Google. I expect Google to remove them in the next 2-5 days.

Can someone tell me whether it's now safe to delete the old /forum/ folder? And do I need to update the .htaccess file once google stops indexing all /forum/ URLs? If yes, what should my htaccess file contain?
